BACKGROUND

The present invention relates to a heating system, and moreparticularly, to a heating system which has a structure that may form afloating floor and in which a heating means is applied to an inner spacebetween upper and lower panels that define a two-layered floor on thestructure.

In general, an access floor is installed in an office room such as acomputer room, an electrical room and an emergency room and is installedin a dual structure such that it is spaced apart from a bottom surfacefor the purpose of concealment of electric wires and the like, blockingof moisture and interior decoration of a floor.

That is, because a number of servers and devices are installed in theelectrical room or an equipment room of a company, power cables, LANcables, private lines, telephone lines and the like are required. Thus,the access floor refers to a construction material that allowsinstallation of a dual floor having a space below a floor such that allthe wires may be used without obstructing passage.

However, the access floor is used only for a floating floor structure.

Meanwhile, in a current heating system for an apartment, a floor isfinished by constructing a heat-insulating sound-absorbing member suchas expanded polystyrene, foamed urethane and foamed polypropylene thatare combustible sound absorbing materials or shock absorbing materialson a slab, forming a lightweight foamed concrete layer thereon, laying ahot water pipe that is a heating member thereon, and constructing amortar layer thereon again.

Such cement construction of the floor structure is totally performed byfield technicians in a wet scheme.

Such an existing technology has problems in that construction isdifficult, maintenance and repairs when water leaks are generated aredifficult because a large amount of pipe connecting members are arrangedinside a concrete layer, a large amount of times are consumed forheating because hot water circulating pipes are connected in series toeach other, and floor noise is transferred well because mortar for aheating pipe is integrated with the floor as well.

To solve the problems of such a wet heating system, a hot water pipe isembedded in a panel formed of concrete, synthetic resin or yellow ocheror a dry heating panel having a groove or a fixing member into which thehot water pipe is inserted is developed and provided.

Such a dry heating panel, which is a prefabricated heating system, isconstructed in a scheme in which pre-manufactured dry panels are simplyassembled on the spot, so that there are advantages in that aconstruction period thereof is shortened and maintenance thereof is easyas well. However, because the panel is manufactured such that theinterior thereof is dry, there are problems in that solidity thereofdeteriorates and there is no heat storage function.

The outer walls 12 are formed on all sides of the upper panel 10 toprotrude downward from a flat aluminum plate, and the fastening bosses18 having fastening grooves 18 a between the fastening bosses 18 and theouter walls 12 are formed by bending predetermined points of the outerwalls 12 twice.

That is, each fastening boss 18 and the corresponding outer wall 12 havean approximately “7” shape when viewed from below as illustrated in FIG.3.

Further, the corresponding catching step 17 and the correspondingcatching boss 16 are formed on sides of the fastening boss 18 and theouter wall 12, which are close to the corresponding fastening groove 18a, at different heights.

When viewed from insides of edges in which the outer walls 12 areformed, fastening holes are formed at centers of the structure seaters11 formed in four locations that may support loads such that the upperpanel 10 may be fixed to a structure 50 constituting a floating floor,the upper panel 10 is fastened to the structure 50 through the fasteningholes of the structure seaters 11 using pieces 31 such as screws, andfinishing caps 32 are inserted into upper portions of the upper panel10.

Further, when there is no leg, the protruding structure seaters 11 donot protrude from a bottom surface of the lower panel, and thus theentire bottom surface of a heating panel 60 is seated on the structure50, so that only structure fasteners (not illustrated) may be used forthe upper panel.

Further, when the heating panel 60 is installed in the structure 50,because loads of the heating panel 60 is focused on legs of thestructure seaters 11, threads are formed and fastening is performedusing nuts N from below, so that the heating panel 60 may be supported.

Here, when the size of the upper panel 10 is enlarged, a structureseater 11 may be additionally formed at a center of the upper panel tosupport a load at a central portion of the upper panel 10.

Further, the upper panel 10 includes the protrusions 13 for enhancingbinding between the upper panel 10 and inner filling materials whencement mortar or yellow ocher is filled in the fastening grooves 18 a,the structure seaters 11 and the panel, the protrusion fasteners 14 forcoupling with the lower panel 20, and the ribs 15 for improving soliditybetween the catching protrusions 16 in the fastening grooves 18 a andthe upper panel 10.

Here, an insulation (not illustrated) having no elasticity may befurther interposed between the structure 50 and the heating panel 60such that the heat is not leaked.

In the above-described Korean floor heating system panel 60, when thebent parts 21 a of the lower panel 20 are properly pushed and insertedinto the fastening grooves 18 a formed at front, rear, left and rightedges of the upper panel 10, the fitting bosses 23 of the lower panel 20are caught by and coupled to the catching protrusions 16 formed insidethe fastening grooves 18 a, and at the same time, while the bent parts21 a of the lower panel 20 are inserted into the fastening grooves 18 a,ends of the bent parts 21 a are caught by the inner catching steps 17,so that the upper panel 10 and the lower panel 20 are dually coupled toeach other.

Next, the bolt fastening holes 22 of the lower panel 20 arebolt-fastened to the protrusion fasteners 14 of the upper panel 10,which have threads on bottom surfaces thereof.

In this way, cement mortar, yellow ocher or the like is filled in anempty space inside the panel in which the upper panel 10 and the lowerpanel 20 are coupled to each other, through the filling holes 24, and iscured. Thereafter, the heating panel 60 is completed.

FIG. 7 is a system diagram illustrating a state in which heating watercirculates in heating panels connected to a boiler according to theembodiment of the present invention.

As illustrated in FIG. 7, a hot water supply pipe 71 and a return waterpipe 72 connected to a boiler B are connected to a branch port 73 and areverse branch port 74, respectively, and an outlet of the branch port73 and an inlet of the reverse branch port 74 are connected to the hotwater supply pipe 35 and the return water pipe 36, respectively.
